STATEMENT REGARDING FEDERALLY SPONSORED RESEARCH OR DEVELOPMENT

Not applicable

BACKGROUND OF THE INVENTION

I. Field of the Invention

This invention is generally directed to the field of agriculture machinery, and more particularly, it relates to a preplanting tillage implements generally used in combination with a seed planting device. Specifically, the invention relates to rolling basket tillage implements, trash moving or trash whipping devices and coulter devices, usually used in tandem with a seed planting implement in which the rolling basket, trash whip and/or coulter devices may be used in various combinations and may have an independent height or deployment adjustment aspect.

II. Related Art

In the spring, prior to planting, farmers must prepare their fields for accepting seed. Many tillage implements have been designed and are used to condition the soil in preparation for planting. Traditional farming includes both primary and secondary tillage tasks to prepare the soil such as plowing, disking, field cultivating and harrowing. Disking is an example of a method of primary tillage and harrowing is an example of a method of secondary tillage.

Primary tillage is a first pass over the soil using a soil conditioning implement attached to the rear of a tractor which works deep into the soil. The soil is usually worked about four inches deep to break up clods of soil, remove air pockets, and destroy weeds deep in the earth. Secondary tillage involves another pass over the same soil, at a more shallow depth, using implements which are generally attached to the rear of the primary tillage unit such that the secondary tillage unit follows the primary tillage unit. The secondary tillage unit generally works the soil to a depth of about two inches.

The secondary tillage unit is usually a final conditioning tool to prepare the soil for planting. Various units may chop up crop residues, or move them out of the way of rows to be planted, break up soil clods and break up any crust on the top of the soil, provide seed furrows, weed control, incorporate chemicals into the soil, and stir and firm the soil closer to the surface.

Rolling basket seedbed finishers represent an important type of secondary soil conditioning implement. Rolling baskets are primarily used as soil leveling devices to break up and minimize clods of soil and to remove air pockets from the soil. Farmers obtain great benefit from using rolling baskets as a means of secondary tillage to provide a level soil for planting. The ability to break up clods of soil, remove air pockets and further incorporate chemicals generally leads to better crop yields at harvest.

In addition to rolling basket seedbed finishers, other agriculture implements are also generally used in preparing the soil for planting. These include a trash whipping-type device which includes a pair of spiked disks normally mounted on a triangular mount which are used to move debris out of the way prior to soil conditioning. Other soil conditioning tools which might be mounted before seed planting implements include coulter devices which employ a sharp steel wedge that cuts vertically and provides a shallow furrow through the soil.

Accordingly, it would be beneficial if a secondary tillage operation using a rolling basket could advantageously be combined with a planting operation such that one could take immediate advantage of soil in condition for planting by accomplishing the planting project during the same pass over a field. Thus, the attachment of rolling basket tillage for use in conjunction with a seed planting implement would be desirable.

However, the use and effectiveness of rolling baskets or other soil conditioning implements is greatly limited by the condition of the soil. If the soil is too wet, rolling basket soil conditioning implements may become filled and clogged with soil which make them useless for further soil conditioning until they are again emptied of soil. When a farmer realizes that areas of soil in a field are too wet to use such implements, he will generally forego the use of such soil conditioning implements entirely for the season. This means that much of the soil may not be properly treated and an expensive farming implement will lay idle. This is not a desirable or economically efficient situation for farmers.

It would, therefore, also be beneficial to provide an arrangement or mechanism that enables intermittent use of a soil conditioning implement, particularly a rolling basket seedbed finisher, and/or a planter in a field where areas of soil are dry enough for use, but where there are also areas which are too wet for use. Such a device would allow a farmer to raise rolling basket seedbed finishers above the soil and out of use whenever they reach a section of a field where the soil is too wet and thereafter enable the rolling basket finisher to be lowered and reconnect with the soil in areas where the soil is suitable for use.

Trash moving or trash whip devices represent another type of equipment which can be advantageously added to a row crop planter to handle amounts of crop residue often present on a field to be replanted, particularly if no till farming is being employed. Minimal till or no till farming leaves an amount of crop residue on a field which may interfere with subsequent seeding operations and so needs to be moved aside from planted rows. The trash whips normally include pairs of angled disks with radially directed teeth or spikes which move crop residue out of the way in advance of planting. The trash whips are normally mounted so that the angled disks form a V-shape and they may or may not overlap.

One problem associated with the operation of trash whippers is controlling the depth of operation of the disk spikes in the field. Some of the present trash whipping devices are mounted at a fixed vertical distance from a tool bar on a planter. The height is adjustable between a series of fixed vertical location settings only. There is no independent control over the force exerted by the implement. Some other current trash whipping devices use air cylinders to modulate resistance in one direction.

Thus, if the lift force or down pressure force on the trash whipping device could be controlled and adjusted, as needed, it would present a distinct advantage.

SUMMARY OF THE INVENTION

The present concept is related to combining said conditioning implement in the form of rolling basket seedbed finishers with planters to accomplish multiple tasks in a single pass. An aspect of the present concept relates to mounting rolling basket seed finishers on planting equipment. A further aspect of the present concept is related to a mounting assembly for a soil conditioning implement in the form of a rolling basket seedbed finisher. The mounting assembly is for individual rolling baskets which are a part of a plurality of such soil conditioning implements generally arranged in a spaced aligned manner on a multi-row planter, seed drill or other implement, which is used to distribute seeds into the soil, hitched to and pulled by a tractor or other prime mover.

Certain embodiments of the mounting assembly include a height adjustable mounting arrangement for each of the rolling basket soil conditioning implements. Each height adjusting mechanism includes an actuator for adjusting the relative height of a corresponding rolling basket individually, and an associated control system for operating the height adjusting mechanism. The actuator preferably includes a hydraulic or pneumatic cylinder, which may be single or double acting. It is also an aspect of the present invention for the mounting assemblies and associated implements to be combined with a planter and arranged such that rolling basket soil conditioning takes place in front of each individual seed planting unit on a planter.

In a preferred embodiment, each mounting assembly for each rolling basket soil conditioning implement may be controlled from a central control system that includes control switches or a control pad, or the like, having a control device associated with each rolling basket located in the cab of an associated tractor. In this manner, a user is able to adjust the height of each mounting assembly individually and therefore the height of each associated soil conditioning rolling basket implement may be adjusted individually as needed.

It will be appreciated by those skilled in the art that a plurality of actuator devices such as pneumatic or hydraulic cylinders, or the like, together with the necessary controls can be connected to be operated from the cab of a tractor or other farm implement device prime mover by conventional means in a well known manner.

In other embodiments, the rolling basket devices may be fixed to the planter and other mechanical devices may be used to apply varying degrees of force to the soil being processed. These include compression or torsion springs, inflatable airbags, shock absorber devices which may be spring loaded, or the like.

Airbag systems may be single or double acting and an embodiment is shown with dual airbags. Single and dual airbag systems are also shown in embodiments in which trash whipping devices and/or coulter devices are attached to the planter.

With regard to the various agriculture implements that are associated with seed planters, it will be appreciated that various combinations of implements can be mounted to a planter and this may be accomplished in a number of ways. Thus, trash whipping devices may be mounted together with coulter devices on the same mounting structure or on separate spaced mounting structures. A coulter and rolling basket combination may be used in which the rolling basket device is split into side-by-side sections and the coulter device is mounted between the rolling basket sections. This provides a combination implement that can also be mounted with a trash whipping device. A whipping implement can be mounted with a unitary rolling basket or coulter device.

Whether the soil conditioning implements are mounted singly or in combination, the deployment of each can be controlled using different systems. One deployment system features employing an adjustable down force only airbag or other device, when released, allows the implement to float or coast along the top of the soil. In other systems, both adjustable down force and up force or lift devices, which may be pneumatic devices such as airbags, are employed in various configurations and using a variety of mechanical linkages. These include a variety of in-line arrangements which may be generally horizontally or vertically disposed. As used herein the term “air bag” is defined to include any expanding inflatable actuating device and which may be single or double acting; single or multiple convoluted structures are also included. The lift devices generally raise the implement above the level of the soil.

DETAILED DESCRIPTION

This description of the preferred embodiments is intended to illustrate representative examples of inventive concepts and is not intended to be limiting as to the scope of the concepts. The examples are to be read in connection with the accompanying drawings, which are to be considered part of the entire written description of this invention. In the description, relative terms such as “lower”, “upper”, “horizontal”, “vertical”, “above”, “below”, “up”, “down”, “top” and “bottom” as well as derivatives thereof (e.g., “horizontally”, “downwardly”, “upwardly”, etc.) should be construed to refer to the orientation as then described or as shown in the drawings under discussion. These relative terms are for convenience of description and do not require that the apparatus be constructed or operated in a particular orientation. Terms such as “connected”, “connecting”, “attached”, “attaching”, “join” and “joining” are used interchangeably and refer to one structure or surface being secured to another structure or surface or integrally fabricated in one piece, unless expressively described otherwise.

An aspect of the invention is directed to an adjustable mounting bracket assembly for attaching a soil conditioning implement in the form of a rolling basket device, particularly to the frame of a planter.

As shown in the embodiment of FIGS. 3-8, the mounting assembly 2, for a rolling basket soil conditioner 10 comprises at least three parts, a height adjustable mounting 4, a height adjusting mechanism or actuator, which may be in the form of a hydraulic (6A in FIG. 9E) or pneumatic cylinder 6, and an associated control system (FIG. 10) for operating a plurality of such height adjusting mechanisms to adjust the height of a plurality of spaced associated connected rolling baskets as normally used in tandem with a planter as towed by a tractor.

As illustrated in FIG. 3, the height adjustable mounting 4 is composed of several parts including an attachment plate 12 and a pair of spaced parallel side plate members 16 and attachment arms 18 for coupling the rolling basket soil conditioning implement to the attachment plate 12. The attachment plate 12 is adapted to be fixed to the frame of a farming implement in the form of a conventional planter along with the attachment plates of other units such that the soil ahead of each planting unit is conditioned.

Each mounting assembly includes spaced arms 18 which extend away from an associated rolling basket soil conditioning and leveling implement 10 which is journaled for rotation between the arms 18 as at 20. The arms 18 connect to the members 16 fixed to the attachment plate 12. The arms 18 are connected to each other by a common crossbar 24 which also supports one end of a cylinder or actuator 6.

As illustrated in FIGS. 3 and 4, the arms 18 and the members 16 of the attachment plate 12 are designed such that they pivotally connect to each other. Any manner known in the art which connects and enables the arms 18 to pivot at 22 relative to the members 16, such as bearings, bushings, etc., can be employed so that the adjustable mounting 4 is able to move towards and away from the surface of the ground with the operation of cylinder 6 which may be attached using a clevis arrangement as at 26 to attach the rod end and a bracket arrangement as at 28 to attach the blind end of the cylinder 6 to the attachment plate 12.

The height-adjusting actuator 6 may be a hydraulic or pneumatic cylinder, or other devices, as illustrated, those skilled in the art will recognize that any mechanical mechanism able to raise and lower the soil conditioning implement 10, as shown in FIGS. 5 and 6, may be used. Thus, in some embodiments, height adjusting depends on raising the planter with the rolling baskets attached. In those embodiments, downward force may be provided by a spring-operated mechanism, an inflatable air spring, or any similar system known in the art, such as are shown in FIGS. 9A-9D. As indicated, several preferred embodiments utilize pneumatic cylinders as compressed air is generally available on tractors to connect to and operate farm implements. It will be recognized, however, that hydraulic systems are also commonly used in these types of applications.

The rolling basket units 10 further include a pair of side plates 30 connected by a plurality of spaced steel bars 32 which may be internally or externally attached to the plates 30. A central spindle or axle 34 is also provided.

FIGS. 5, 6A, 6B, 7A and 7B also depict a planting implement 35 having a seed distributing arrangement 36 (FIG. 6B) and a connecting frame 37 including a main structural member 38 that connects together a plurality of similar units 35.

As shown in FIGS. 5 and 6A, the operation of the actuator 6 serves to raise and lower the soil conditioning rolling basket implement 10 in accordance with the operation of a control system. It should be noted that in an implement carrying a plurality of soil conditioning rolling baskets 10, as shown in FIG. 10, an associated control system enables the raising and lowering of the soil conditioning implements individually as desired by the operator in the tractor or other towing vehicle. It may also enable the soil conditioning implement 10 to be positioned in a floating mode riding the soil surface or lowered with applied force as needed.

An alternate embodiment of the mounting bracket assembly is shown generally at 102 in FIGS. 1 and 2 and also includes a height adjustable mounting 104. That system utilizes a shell or shroud 114 covering the upper portion of the rolling basket 110. Pivotally connected members 116 and arms 118 are shown together with mounting bracket 120 and clevis attachment 122. The actuating cylinder or other such device is not shown.

FIG. 10 is a schematic drawing of a soil conditioning system used with a multi-row seed planter so that a field may be properly leveled and thereafter receive seeds from the planter modules. In this schematic drawing, a tow bar 40 is connected to a trailer tongue 42 that is adapted to be connected by a clevis (not shown) to a towing work vehicle, such as a farm tractor. Secured to the tow bar are a plurality of rolling basket tillage devices 44.

Primary tillage devices (not shown) may, for example, comprise disk harrows or rake harrows of conventional design known in the art may be used prior to employing the rolling baskets. As previously explained, the primary harrows are arranged to dig deeper into the soil and typically produce clumps depending on soil type and moisture content. It is preferable that the clumps become crushed and broken up and the soil leveled by the action of the secondary rolling basket devices 44 leaving the field prepared to receive seed at the time of seeding and the seed distributed by planter modules 46.

The user or driver of the tractor or other prime mover determines whether the soil is too wet for the soil conditioning implements 2 to effectively work or not. If the soil is too wet, the user sends a signal via the control system, to activate the height-adjusting mechanism 4. In a preferred embodiment, the height adjusting mechanism is connected to a pneumatic system which has an air compressor 52 for maintaining a predetermined pressure in an accumulator 50. At least one pneumatic solenoid valve 58 is connected between the accumulator and each actuator 6 to control the application of the pressure supplied to the actuator 6. A manifold 58 in FIG. 10 is shown as supplying pressurized air, via solenoid valves 56, to one or more actuators 6 under control of electrical signals from an operator's controller module which includes a key pad control (which may be remote) at 60. A combined electrical and pneumatic connection is shown at 62 and a manifold controller is shown at 64. The system may incorporate a pressure regulator (not shown) to adjust the amount of force (from the pressurized air) applied to raise the soil conditioning implement.

Pressurized air is then supplied to the pneumatic cylinders 6 in a well known manner to the mounting assembly, which, in turn, will raise the soil conditioning implement if the user has determined the soil in that location is too wet for use, or lower the soil conditioning implement if the soil is suitable to use the soil conditioning implement. It will be appreciated that the cylinders 6 may be single or double acting with single acting cylinders used to raise the soil conditioning implements on the power stroke and allow the basket to float under its own weight when the pressure is released. Double acting cylinders can be used to fix the implement in a lowered position.

As also shown in FIG. 10, each of the plurality of rolling basket soil conditioning assemblies may be placed in front of each of a plurality of seed distribution units of a planter as at 46 to ready the soil to receive the seeds. Each of the mounting assemblies for the soil conditioners may be controlled individually or simultaneously with others. Also, groups of mounting assemblies may be controlled. If the mounting assemblies are controlled individually, the manifold 58 (either pneumatic or hydraulic), may supply pressurized air through the use of solenoid valves 56. The operator is able to control the height adjustment and so the application of one soil conditioning implement, a specific group of soil conditioning implements, or all of the soil conditioning implements using the control pad 60 in the cab of the tractor. As indicated, the control pad 60 may be any kind known in the art for sending control signals to solenoid or other pneumatic or hydraulic valves.

The system allows for maximum efficiency of the soil conditioning implements, for if one row or a few of the rows in a field are too wet, but the remaining rows are dry, the user may selectively apply the soil conditioning rolling basket implements to suitable rows. The user, therefore, is able to maximize the effect of using rolling basket soil conditioning devices in a field.

FIG. 7A depicts a rolling basket device 10 in accordance with the invention fixed to the main structural member 38 of a planting implement, a unit of which is shown at 35 in which the attachment plate 12 is attached to the member 38 by an additional framework 70. A similar arrangement is shown in FIG. 7B in which the actuator is a double acting airbag system as at 72.

FIGS. 9A-9E depict alternative actuator devices used in combination with the rolling baskets. They include a pair of torsion springs as at 80 in FIG. 9A which are used to provide an amount of downward force on the rolling basket 10. Similarly, FIG. 9B utilizes a compression spring 82 connected between mounting plate 12 and cross member 24. A spring and shock absorber arrangement 84 is shown in FIG. 9C and a single acting airbag or air shock absorber is shown in FIG. 9D.

It should be noted that rolling baskets having mounting arrangements with devices providing downward force only are normally raised manually when they need to be out of contact with the soil. They are held in a raised position using a manually-operated latch system such as is at 88 shown in FIG. 9F.

Another embodiment is shown in the several views of FIGS. 11A-16 in which dual airbags or inflatable pneumatic actuators are used to lower or deploy and raise or retract the rolling basket. This rolling basket system is shown generally at 200 and includes a rolling basket 202, which is mounted to a height-adjusting mechanism 204 using a pair of spaced parallel side plate members 206 and 208, which are fixed to a lower assembly 210, which includes a main member 212, which may be in the form of a heavy tube member, and which connects to the side plate members 206 and 208. The lower assembly, with the side plate members 206 and 208, in turn, pivots around a pair of spaced, shoulder bolts 214, which connect it to a mounting structure including shaped members 216 fixed to or are part of attachment or mounting plate 218, which, in turn, can be fastened to a main implement such as a multi-row planter, as shown in FIG. 10, at a plurality of places 220 using conventional bolts, or the like, as at 221.

The rolling basket system further includes a down force or deployment airbag arrangement that includes a down force or deployment airbag 222 mounted between a bottom pedestal 224 and a fixed upper bracket 226. The bottom pedestal is mounted to the lower assembly by spaced members 228 and spaced fulcrum members 230 which are fixed to member 212 and members 228 and 230 connected by opposed shoulder bolts 232 such that the pedestal can pivot freely on the shoulder bolts.

The system further includes an up force or retraction airbag arrangement that includes an up force or retraction airbag 234 that is mounted between a moving upper U-shaped bracket 236 and a bent flange member 238. As best seen in FIG. 12B, spaced legs of bracket 236 are also fixed to the lower assembly 210 by spaced fulcrum plates 240 which are fixed to member 212 and the spaced legs of bracket 236 are connected pivotally to fulcrum plates 240 by opposed shoulder bolts 242 on which the bracket 236 can pivot freely.

Air lines 244 and 246 are connected respectively to down force and up force airbags 222 and 234 and to a conventional supply of pressurized air not shown. The system is configured so that, when high pressure air is introduced to inflate one bag, the other bag can deflate.

FIGS. 11A, 11B and 15A-15C show the lower assembly 210 and basket 202 in the deployed or down position with the down force airbag fully inflated. As the down force bag 222 inflates, it causes the lower assembly to pivot downward and deploy the basket 202 downward. The act of the lower assembly moving downward causes the bracket 236 connected to lift bag 234 to be displaced downward forcing air out of and collapsing the lift bag, as shown in FIG. 11B. Conversely, as shown in FIGS. 12A, 12B, 13B and 14A-C, to raise or retract the lower assembly 210 and basket 202, the lift bag 234 is fully inflated, which causes the bracket 236 to move upward and the lower assembly to rotate upward about shoulder bolts 232 and 214, which, in turn, causes the bottom pedestal 224 to be displaced upward and this collapses or deflates down force airbag 222. The lifting force of the airbag 234 is transferred to the lower assembly 210 through bent flange 238. Shoulder bolts 242 connect the legs of bracket 236 with fulcrum members 240.

It will become apparent that each of the shoulder bolts that transfer force from the airbags to the lower assembly travel pivotally about a fulcrum, as best shown at 230 and 242 in the figures. The fulcrums, in turn produce an arcuate motion of the side plate members 206 and 208, as they raise and lower member 212 and the lower assembly. In that manner, the lower assembly travels along the arc of a circle when deployed and retracted with the main shoulder bolts 214 as pivots.

FIGS. 17A-17C and 18A-18B depict a five-port air valve assembly in two alternate positions. The assembly, generally at 300, includes ports 302, 304, 306, 308 and 310 and cylinder 312, housing axially adjustable cylinder valve 314. The valve body or block is depicted at 316. Ports 302 and 306 are connected to receive air from a high pressure air source such as a conventional compressor system (not shown). Ports 308 and 310 connect respectively to the up force airbag and the down force airbag. Finally, port 304 is a vent port for venting air from either the up force airbag or the down force airbag.

In FIGS. 17A and 17B, the port receiving high pressure air 306 is connected through the valve block with down force bag 222 through outlet port 310 with the central valve 312 shifted to the left in cylinder 314 in a first position shifted to the left. With the central cylinder in this position, up force airbag 234 is connected to the vent port 304 via port 308 so that up force airbag 235 is enabled to collapse while down force airbag 222 inflates. This deploys the rolling basket against the ground.

FIGS. 18A and 18B show the valve 312 in an alternate position with the central cylinder moved to the right. With the central in this position, port 302 is connected through the central cylinder to port 308 and port 310 is connected to the central cylinder to port 304 and port 306 is deadheaded. With the valve in this position, the source of high pressure air is connected through ports 302 and 308 to the up force airbag and the down force is connected to vent through ports 310 and 304. This will enable the up force airbag to inflate and the down force airbag to collapse in accordance with raising the rolling basket to an up or stowed position.

Another embodiment is shown and illustrated in the several views of FIGS. 19A-23B which, like the embodiment shown in FIGS. 11A-16 employs dual airbags or inflatable pneumatic actuators to lower (deploy) and raise (retract) an agriculture implement. In this embodiment, the implement is a trash whipping-type device. As shown in FIGS. 19A-19F, 20A-20C, 21A-21C and FIGS. 23A and 23B, the trash whipping system, generally at 400, includes a pair of spiked disks 402 and 404 with dirt guards 406 and 408, respectively, mounted on a triangular mount 410 (FIG. 23A) by means of a pair of bent flanges 412 and 414. A main mounting cross member, preferably a tube member, is shown at 416 and a connecting tube 418 has a fixed end fixed to the main mounting tube 416 and a free end that carries the triangular mount 410. The connecting tube is preferably connected directly to the back of the flanges 412 and 414 as by welding. The main member 416 is connected to a mounting structure by heavy side plate members 420 and 422. As with other embodiments, side plate members 420 and 422 pivot around a pair of spaced shoulder bolts 424 which connect the members 420 and 422 to the mounting structure including shaped members 426, which are fixed to or are a part of attachment or mounting plate 428 which, of course, can be fastened to a main implement such as a multi-row planter with a plurality of other spaced trash whipping systems at a plurality of places using conventional bolts, or the like, using openings 430. A similar system is shown in FIG. 10 with respect to rolling basket embodiments.

It will be appreciated that the mounting system of the invention can be used with many different disk varieties and those shown at 402 and 404 are for illustration purposes. They can be used with or without dirt guards also.

The trash whipping system further includes a down force or deployment airbag arrangement that includes a down force or deployment airbag 432 mounted between a bottom pedestal 434 and a fixed upper bracket 436. The bottom pedestal is mounted to the lower assembly by spaced members 438 and spaced fulcrum members 440 which are fixed to member 416 and members 438 and 440 connected by opposed shoulder bolts 442 such that the pedestal can pivot freely on the shoulder bolts.

The system further includes an up force or retraction airbag arrangement that includes an up force or retraction airbag 444 that is mounted between a moving upper U-shaped bracket 446 and a bent flange bracket member 448. As best seen in FIGS. 19F, 20A and 21C, spaced legs of bracket 446 are also fixed to the lower assembly main tube 416 by spaced fulcrum plates 450 which are fixed to member 416 and the spaced legs of bracket 446 are connected pivotally to fulcrum plates 450 by opposed shoulder bolts 424 on which the bracket 448 can pivot freely.

Air lines are connected respectively to down force and up force airbags 432 and 444 and to a conventional supply of pressurized air (not shown). The system is configured, as will be described.

FIG. 22 depicts a control system for the trash whip assembly in the lifted or stowed position. The system includes an electronic regulator 500 which can be set to control output pressure and thus, the pressure in a connected airbag over a wide range. A manual regulator is shown at 502.

In FIG. 22, air coming from a supply such as a compressor accumulator tank (not shown) is supplied to regulators 500 and 502 at 504 and 506, respectively. Output streams from the regulators 500 and 502 are shown, respectively, at 508 and 510.

In the diagram of FIG. 22, the down force pressure supply 516 entering port 506 is supplied constantly at a suitable pressure to act as a shock absorber to the down force airbag through 510, typically, 18-20 lbs. Air is supplied to adjustable electronic regulator 500 through an input port at 504 and air is supplied to up force airbag through an output port at 508. It will be appreciated, however, that air is being supplied to both the down force airbag and the lift airbag.

With air being supplied to both the lift and down force airbags, a state of equilibrium can be achieved and maintained with the whipping device in any desired position of mechanical resistance with respect to the deployed mechanism. This disposition also allows the operator to vary the net upward or downward force as desired using the electronic regulator 500. Of course, the electronic regulator 500 can also be replaced by a manual control, if desired. In this manner, the trash whipping device can be controlled to exert any desired downward force or be controlled to float, just skimming the top of the soil. This achieves a continuous operator-directed control over the operation of the trash whipping device which has been demonstrated to be highly successful. It will be appreciated that other implements could be mounted on and controlled by this system.

FIG. 24 is a side elevational view including a planting implement, generally at 600, which may be a conventional commercial planter. The drawing depicts a trash whipping device 602 which may be similar to those previously described and a coulter device 604 which includes a blade or wheel 606 attached via a mounting member 608 to a mounting structure or assembly 610. Raising and lowering of the coulter device 604 is enabled via rotation of the member 608 about a joint 612. An inflatable airbag for applying a downward force to deploy the coulter disk 606 is shown at 614. The mounting assembly 610 carries both the trash whipping device and the coulter.

A front view of the assembly of FIG. 24 is shown in FIG. 25A with the trash whip disks removed revealing the triangular mount 620 and a pair of dual airbags 622 employed to raise and lower the trash whip in a manner as previously described for other embodiments. In FIG. 25B, a rear view is depicted showing single airbag 614 which may be utilized when desired to apply a downward force on coulter disk blade 606. When the downward force is released, the coulter device will simply ride along on top of the soil. As shown in FIG. 24, the common mounting assembly 610 is connected to the planting device 600 by a pair of members 616 shown in FIG. 25A.

FIGS. 26 and 27A and 27B depict rear perspective and front and back elevational views of a planter as in FIG. 24 to which a trash whip is attached, together with an implement that combines a rolling basket with a coulter device. Both implements are mounted on the common mounting structure or assembly 610. The combination of rolling basket and coulter device 630 is carried by a pair of attachment members 632 which allow rotation of the coulter disk 606 and rolling basket sections 634 and 636 and also enable vertical displacement by pivoting about joints as at 638. They are carried by a common shaft 640. As with the coulter embodiment of FIGS. 24 and 25B, combination device 630 is operated by a single down force deployment airbag 614. Releasing the down force, of course, enables the device to simply roll along on top of the soil. This combination enables the planting operation to accomplish the actions of all three agricultural implements in a single pass.

FIGS. 28 and 29A and 29B depict a side elevation view showing a combination of a trash whipping implement 602 with a rolling basket 642 mounted to the common assembly 610 with the rolling basket having a down force only airbag deployment system 614 and the trash whipping device having dual-acting up/down airbags. As with the other down force only devices, when the down force is released from the airbag 614, the rolling basket 642 will simply float or roll along the surface of the ground in a harmless manner.

FIG. 30 is a front perspective view showing a common mounting structure for the trash whip and rolling basket in which the rolling basket is deployed with a down force only airbag. The common mounting structure 610 includes a box shape 650 which receives the front end of two connecting members 616, the other end of which connects to a mounting plate 652 which, in turn, connects to the main planter device 600 using threaded connectors as at 654. Note that both the trash whip mount 620 and rolling basket 640 are connected through devices from the simple box structure 650. The structure 610 enables implements to be mounted both ahead of and behind the box configuration 650.

FIG. 31 depicts a side elevational view in which a trash whipping device 602 and a rolling basket 640 are attached to a planter implement using two different spaced attachment assemblies 660 and 662, respectively.

FIG. 32 depicts a front perspective view of the assembly of FIG. 31. In this embodiment, the rowbasket 640 is deployed and retracted using a dual airbag system with airbag 664 shown in the perspective view. A slightly enlarged side elevational view of the assembly of FIGS. 31 and 32 is depicted in FIG. 33. The mounting system 666 shown for the trash whip device is quite similar to embodiments described earlier with regard to the use of the trash whip as a single device, as illustrated in FIGS. 20A-21C. Likewise, the mounting assembly 668 for the rolling basket 640 can be similar to that shown in FIGS. 14A-16. Such a mounting system, as shown in FIGS. 31-33, is particularly useful when combinations of soil-treating devices are added in tandem to existing planter combinations. A top view of the system of FIGS. 31-33 is shown in FIG. 34 and, in that figure, both the rolling basket and trash whip devices are operated using a dual set of airbags so that both down force and up force are available in deploying and retracting the devices.

A further embodiment is shown in FIGS. 35A-D in which a height-adjustable trash whipper mounting assembly is mounted in combination with a rolling basket device. The embodiment is shown generally at 700 and includes a mounting arrangement for a trash whipping device at 702, a mounting system for a rolling basket at 704 and a system for attachment to a planter or transversely extending tool bar attached behind a tractor at 705.

The trash whipping mounting frame assembly includes a vertically adjustable parallel bar linkage system having pairs of upper and lower parallel linkage members 706 and 708 spanned by pairs of generally transverse U-shaped member 710 and a pair of generally vertical side members 712. Only one of each of the paired member is shown in a particular view, but the mounting assembly has two symmetrical, generally identical opposed sides. The members 710 carry triangular trash whipper mount 714. The members 706 and 708 are mounted to pivot as at 716 and 718.

The trash whipper mounting assembly is controlled to operate generally vertically by two opposed pneumatic actuators or operators which may be a lift force air bag 720 and a down force air bag 722 that are mounted in aligned fashion to push in opposite directions against a centrally located plate member 724 which in turn is connected to members 712 to pivot the linkage structure up and down to retract and deploy a device or tool attached to the triangular mount 714.

Movement of and force exerted on the linkage is determined by the relative inflation of the aligned air bags and this can be used to position the associated implement or tool and modulate the force exerted by the tool on the soil. Generally when the tool is to be stowed in the fully raised position the down force operator can be vented and collapsed. FIG. 35A depicts the linkage members 706 and 708 in the up position, the central plate member 704 having been displaced upward with the lift operator 720 being under more pressure than the down force operator 722. Conversely, in FIG. 35B the pressure in the down force operator 722 exceeds that in the up force operator thereby displacing the member 714 downward. It will be appreciated that the relative net force exerted on a mounted tool can be controlled quite accurately.

The rolling basket mounting system is best shown in the side elevational views of FIGS. 35C and 35D in which parts have been removed to better view the basket mounting and operating system and which show the basket 730 in a raised and lowered position, respectively. The mounting system a lift force operator 732 and a down force operator 734. These may also preferentially be air bags or the like. The lift force operator pushes against a pair of spaced linkage members one of which is shown at 736 which are spanned by a flange member 738. Each member 736 is pivotably connected to a shaped lift lever 740 which has a fixed fulcrum 742. The free end of lift levers 740 connect to a further link 744 which adds flexibility to the linkage. The lift lever 740 pivots in circular motion about fulcrum 742. Other linkage member 746 connects link 744 and the lift system with a down force system. The FIG. 35C shows the system with the basket in the raised position and the lift levers 740 in the raised position with lift air bag 732 inflated and down force operator 734 deflated.

The down force operator 734 operates against a plate member 750 which is connected to spaced down force levers 752 at 754 to pivot levers 752 about a down force lever fulcrum 756. Members 754 have a free end connected to one end of linkage members 746 and also operate with a circular motion about fulcrum 756 with the moving end operating to transfer downward motion to the rolling basket and using members 746 and pulls down on lift levers 740 when the down force operator 734 is inflated. This collapses or reduces lift operator 732 as shown in the FIG. 35D.

The embodiment is designed to attach to a planter or toolbar as by using a plate 760 with fasteners 762. As shown the two implements can be operated totally independently with the deployment and ground pressure independently controlled.

A further embodiment is shown in FIGS. 36A-36E in which aligned directly opposed pneumatic operators or air bags are employed to control the vertical force exerted on individual planter row seeding units of a multi-row planter. Control of this force enables each individual seeding unit to place its seeds at the correct depth regardless of the contour of the ground in a given field which, as is well known may vary considerably. The system also provides better control over the operation of individual seeding units. A unit is shown in an position in FIGS. 36A and 36B, and in a “down” position in FIGS. 36C and 36D. A front perspective is show in FIG. 36E.

The seeding unit, generally at 800, is attached to a member 802 of a multi-row planter (not shown). The seeding head 804 is attached to move up and down by a linkage having pairs of spaced parallel pivoting linkage members including upper members 806 and lower members 808.

The pneumatic operators are housed within a steel cage 810 and include a lift air bag 812 and a down force air bag 814. A plate assembly 816 attached to the end of a pivoting lever 818 is sandwiched between the air bags 812 and 814. The pivoting lever 818 is attached at 820 to a member 822 to pivot member 808 as the upper end of the member 818 moves back and forth with the inflation and deflation of the axially aligned opposed pneumatic operators. This pivots the parallel linkage correspondingly as shown in the Figures.

While the embodiments illustrated show the combination of certain implements, it is contemplated that other combinations can be used.

It should be noted that any of the implements shown deployed with down force only airbags could also be operated using a dual set of down force and up force airbags and, if desired, other devices can be used to deploy and retract any of the agriculture implements shown. The details of the connections and operation of the airbag deployment and retraction systems is similar to those described in earlier embodiments and need not be described in great detail here. As with other embodiments, the down force can be modulated as desired.
